https://youtu.be/rok4lQ3pPsA I designed this case for the "Lilygo T-Display-S3 Touch Development Board" which features a 320 by 170 color display and a touch screen. I'm planning on using this board in upcoming projects and decided to create this case for it. In order to learn the development board features, I wrote software in the Arduino environment for a simple four function calculator. Our grandkids love playing with this tiny calculator, and their fingers fit the keypad better than mine! I hope you enjoy it! As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes. Software designed using Arduino environment, case was designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1 and 3D printed in PLA on Ultimaker S5s.
